Finally , the level identification , classification of these nine endophytic fungi are studied through literature retrieving and comparison with related genus or type species , during which the characteristics of conidia and the result of physiological experiment are regarded as key words and as assist respectively . the ultimate result of these strains " classification are that one new species coniothyrium macrospora y . xiang et j . x . cui sp . nov . ( 1026 ) ; five new recorded - genus in china : papularia sphaerosperma ( pers . ex fr . ) 以形态学性状中的分生孢子特征为主题,以生理实验结果为辅助,检索文献,与相关种和模式种进行对照比较,对这些内生真菌进行水平的菌种鉴定分类,其中菌株1026为一新种:大孢盾壳霉( coniothyriummacrosporay . xiangetj . x . cuisp . nov . ) , 5株为中国新记录属种: 1005球乳突孢[ papulariasphaerosperma ( pers . exfr . ) vonh (
During the last two years , i checked the miter specimen collection of mbmcas collected by the explorations since 50 decade of last century , including " the comprehensive resource investigation of chinese coast and shallow waters " ( 1958 - 1960 ) , " china - vietnam cooperative expedition of marine resource to beibu bay ( gulf of tokin ) " ( 1959 - 1962 ) , " the resource investigation of coast and shallow waters of shandong province " , " the comprehensive resource investigation of the islands of china " , " china - germany cooperative expeditions of marine biota to hainan island , china " ( 1990 - 1992 ) , and 52 species have been found , which are mainly from east and south china seas , of which , three forms are considered as new species , i 中国科学院海洋研究所从50年代以来进行的若干次海洋生物考察过程如全国海洋综合调查、 “中越北部湾海洋综合调查” 、 “中德海南岛生物联合考察”中获得了大量的笔螺科标本。作者以传统的形态分类为主要研究方法,通过解剖、数码摄影等手段进行综合分析,对我国近海笔螺科进行了系统的整理和分类研究。本文对我国所采集到的所有属种进行了详细的描述,并用数码相机拍照,制成彩色图版,其中对易混淆的种类就其形态特征进行分类比较。
In order to offer reference to integrated application of species for tamarix l . in china , this paper discussed the taxonomy , biology and physiology characteristics of tamarisk , reviewed the research advances on investigation , identification and evaluation , collection and storage of germplasm resources of tamarisk l . , and summarized genetic breeding , seeding seedlings , cutting seedlings and tissue culture of tamarisk l . so as to put forward the direction of innovative research and application based on indicated problems in research of germplasm resources of tamarisk l 摘要为了为柽柳属植物的综合开发应用提供参考依据,文章论述了柽柳属植物的生物学和生态学特性,综述了我国柽柳属植物种类的资源调查、鉴定评价、收集保存及引种育种情况,总结了国内柽柳播种育苗、扦插育苗和组织培养育苗的研究现状,指出了柽柳属植物种质资源研究方面存在的问题,提出了柽柳属种质资源创新研究和开发利用的建议。
In the present study , eighty - one species of suborder flabellifera are found and described , of which 13 are new species and the other 29 species are recorded for the first time from chinese waters . key to chinese families and genera are provided . discussion on taxonomic problems is given and brief notes of the distribution are provided 本文以传统的形态分类为主,结合现代分类学的手段和方法解决近似种、疑难种的准确鉴定问题,搞清中国的属种及分类上存在的错误和混淆,并结合已有的此类群研究结果,进行地理区系的比较。
In the first , the research development and problems in the taxonomical systematics of lycoris were summarized in the article , including the research of germplasma resources and exploitations , artificial cultivation , tissue culture , physiology , morphology , pharmacology , decorative values and molecule 本文首先综述了石蒜属植物的研究进展及分类系统学上存在的问题,包括石蒜属种质资源的开发利用、人工栽培和组织培养、生理、形态、染色体、药用和药理、观赏价值以及分子方面的研究。
The conodont fauna of late permian to early triassic from yangou section in leping area , jiangxi province was discussed in this paper . all of the conodont individuals founded in this section were listed in a figure . according to the distribution of the important conodont elements , this section was divided into three conodont zones from the upper permian to the lower triassic 讨论了赣中乐平地区沿沟剖面上二叠统至下三叠统地层的牙形石动物群,列出了牙形石的各个形态属种在地层中的分布及其数量变化。根据特征牙形石分子的地层分布,将该段地层自下而上划分为3个牙形石带,分别是:
These findings , on one side , broaden current knowledge about the early evolutionary history of the lycopsid characters , and on the other side , indicate that those satellite taxa should also be taken into consideration besides those whole or almost whole species when making a phylogenetic analysis 这些植物既拓宽了对石松植物整个谱系的性状演化的认识,也暗示在进行谱系分析及分类时不仅要基于一些整体植物种或者接近完整的属种,而且必须重视众多卫星分类单元的系统位置以及它们的演化意义。
The study of neogene calcareous nannofossils from the pearl river mouth basin in the last two decades could be subdivided into two stages ( 1 ) from the beginning period of the 80 ' s to early of the last century , the studies focused on the calcareous nannofossil zones and the descriptions of main genera and species ; ( 2 ) from the middle and late period of the 90 ' s of the last century to the present , the researches concentrated on the high - resolution calcareous nannnofossil biostratigraphy 纵观二十多年来珠江口盆地新近系钙质超微化石的研究历史,大致可分成两个阶段: ( 1 )上世纪80年代初至90年代初,侧重于化石带的报道及主要化石属种的描述; ( 2 )上世纪90年代中后期至今,主要为高分辨率钙质超微生物地层研究阶段。
